Effects of L. acidophilus on the Growth, Morbidity and the Number of E. coli of Puppy
摘要
Abstract
By adding L. acidophilus in the diet, an experiment was designed to investigate the influence of L. acidophilus on the growth, morbidity, the number of E. coli of puppy. Sixty German Shepherd puppies from 10 litters were selected and each litter was randomly divided into 2 groups. In the treatment group the milk powder mixed with 3.2 g L. acidophilus had been supplied for the dogs from 20 days , so had the feed stuff from 30 days when the puppy was being weaned. The experimental results showed that L. acidophilus has a significant growth enhancement effect on puppy body weight （ P 〈 0.05）. Dietary L. acidophilus had influence on the feed conversion （ P 〈 O. 05）, decreased diarrhea frequency and mortality, and cut down diarrhea time. Otherwise, it could de- crease faeces pH 0.3 - O. 5, make anaerobic bacteria dominant distribution after being weaned, increase concentration of L. acidophilus and decreased that of E. coli.关键词
